Sounds like a yeast rash. You can get some over the counter cream for for fungal infections (like lotramin or something similar - Nystatin and terbenafine are what I've used before). Use 3x a day. I like triple paste for regular diaper creams. Just remember that most diaper creams are barrier creams so it must be applied to a dry bottom to be effective, otherwise you'll be sealing in moisture. Use the antifungal creams. If it's not a yeast rash it won't do any harm, but you'll know in a day or two if it's making a difference. If the rash is from diahreaa it might be worth the expense of medicated cream to neutralize the pH of the stool. Good luck!
